Husqvarna 45 carb jet blocked

SOURCE: Husqvarna 385

Sounds like dirty carberator or carb needs adjustment. How is the spark plug?

The carb uses the pulses from the crankcase to actuate a diaphram in the carb as the fuel pump.If you strip the carb make sure there are no perforations/cracks etc. on these diaphrams and check too that the valve flaps are OK.if not fit a carb kit.

Also check that the pipe or channel from the carb to crankcase is OK.

If all this is correct you can simply put your hand behind the carb or inlet to check for vacuum if not there you have probably blown a crank seal(but unlikely)and you will have to replace them.

Hope this helps,and please come back if you need any further assistance.

Testimonial: "Thanks again luckyluke I did find it and was able to clean it through I'm still having the problem of not starting though, carb kit next 90lb cyl comp"

Try turning the high idle screw out 1/8 to 1/4 turn refer to your manuel for the location of this screw.

Check the fuel lines for cracks/breaks. If they are o.k., then:

You willneed to disassemble the carburetor and spray with carb.cleaner.Makesure the small screen is free of debris. (Should be able to see daylightthrough it.)

Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.

If the carb. parts are more than 4 years old, you may have to replace them.

If you need further assistance on:
1. Fuel line replacement or
2. Carburetor kit replacement

Just let me know.
